Ubuntu 14.04.1中ros-indigo系列包无法找到的技术求助

Hey there! Let's sort out this issue—since both Ubuntu 14.04 (Trusty Tahr) and ROS Indigo are end-of-life (EOL) versions, their official repositories are no longer hosted on active servers. That's why your package manager can't locate the ros-indigo-* packages you're trying to install. Here's a step-by-step fix:

Step 1: Backup existing ROS sources (if any) #

If you already tried adding the standard ROS repo earlier, make a backup to avoid conflicts:

sudo cp /etc/apt/sources.list.d/ros-latest.list /etc/apt/sources.list.d/ros-latest.list.bak

(Skip this if you don't have the ros-latest.list file.)

Step 2: Add the archived ROS repository #

EOL ROS versions are hosted on the archive server. Replace your current ROS source with this:

sudo sh -c 'echo "deb http://archive.ros.org/ros/ubuntu trusty main" > /etc/apt/sources.list.d/ros-latest.list'

(Note: trusty is the codename for Ubuntu 14.04—make sure this matches your system.)

Step 3: Import the archived ROS GPG key #

The original ROS key might not be trusted anymore for EOL repos. Run this to add the archive key:

sudo curl -sSL http://archive.ros.org/ros.key | sudo apt-key add -

If that fails, try the keyserver method instead:

sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-key C1CF6E31E6BADE8868B172B4F42ED6FBAB17C654

Step 4: Update your package list #

Refresh your apt cache to recognize the new repository:

sudo apt-get update

(You might see warnings about Ubuntu 14.04's own EOL repos—this is normal since Trusty is no longer supported.)

Step 5: Install the ROS package #

Now you should be able to install the desktop full or desktop version:

• For full desktop install:

  sudo apt-get install ros-indigo-desktop-full
  

• For basic desktop install:

  sudo apt-get install ros-indigo-desktop
  

Quick Note #

Keep in mind that Ubuntu 14.04 and ROS Indigo are no longer receiving security updates. If possible, consider upgrading to a newer Ubuntu version (like 20.04 with ROS Noetic or 22.04 with ROS Humble) for better support and security. But if you absolutely need Indigo for your project, the steps above should get you up and running.
